how far can you cantilever a 2×12 deck joist

The maximum distance you can cantilever a 2×12 deck joist depends on several factors, including the type of wood, the span of the joist, and local building codes. Generally, a 2×12 joist can cantilever up to 12-18 inches beyond the supporting beam, but it’s important to ensure the remaining span plus the cantilever does not exceed the joist’s maximum allowable span. Always consult local building codes and a structural engineer for specific requirements in your area.
